Scientific discovery is often regarded as romantic and creative - and hence unanalyzable - whereas the everyday process of verifying discoveries is sober and more suited to analysis. Yet this fascinating exploration of how scientific work proceeds argues that however sudden the moment of discovery may seem, the discovery process can be described and modeled. Using the methods and concepts of contemporary information-processing psychology (or cognitive science) the authors develop a series of artificial-intelligence programs that can simulate the human thought (...) processes used to discover scientific laws. The programs - BACON, DALTON, GLAUBER, and STAHL - are all largely data-driven, that is, when presented with series of chemical or physical measurements they search for uniformities and linking elements, generating and checking hypotheses and creating new concepts as they go along. "Scientific Discovery examines the nature of scientific research and reviews the arguments for and against a normative theory of discovery; describes the evolution of the BACON programs, which discover quantitative empirical laws and invent new concepts; presents programs that discover laws in qualitative and quantitative data; and ties the results together, suggesting how a combined and extended program might find research problems, invent new instruments, and invent appropriate problem representations. Numerous prominent historical examples of discoveries from physics and chemistry are used as tests for the programs and anchor the discussion concretely in the history of science.

Wittgenstein was one of the most powerful influences on contemporary philosophy, yet he shunned publicity and was essentially a private man. This remarkable, vivid, personal memoir is written by one of his friends, the eminent philosopher Norman Malcolm. Reissued in paperback, this edition includes the complete text of fifty-seven letters which Wittgenstein wrote to Malcolm over a period of eleven years. Also included is a concise biographical sketch by another of Wittgenstein's philosopher friends, Georg Henrik von Wright. 'A (...) reader does not need to care about philosophy to be excited by Mr Malcolm's book; it is about Wittgenstein as a man, and its interest is human interest'. (shrink)

The standard theory of electoral accountability treats the electorate as an appraiser of government performance on a range of complex issues, which re-elects or de-elects depending on its evaluation of that performance. This paper draws from studies on voter knowledge and behaviour to present a dilemma for the standard theory: either voters do not know how well their rulers have performed, or if they do, they do not base their votes on that knowledge. It is shown that, on either horn (...) of the dilemma, the standard account of electoral accountability fails, and that attempts to deflate the dilemma through heuristic and aggregative approaches to voter knowledge, or proposals for alternative systems of government, are also inadequate. The paper then sets out and defends an alternative conception of electoral accountability, which holds that electoral accountability is not about micro-assessing a government’s actions. Rather, it is about preventing political rulers from committing or allowing substantial harms to come upon those they govern. This alternative conception is compatible with a realistic view of voter knowledge and behaviour, but nonetheless makes electoral accountability an essential component of a well-functioning democratic system.

Recently some philosophers have proposed that the later philosophy of Wittgenstein tends towards idealism, or even solipsism. The solipsism is said to be of a peculiar kind. It is characterized as a ‘collective’ or ‘aggregative’ solipsism. The solipsism or idealism is also said to be ‘transcendental’. In the first part of this paper I will be examining a recent essay by Professor Bernard Williams, in which he presents what he takes to be the grounds for such an interpretation of Wittgenstein. (...) After that I will try to offer convincing evidence that no tendency towards any form of idealism is to be found in Wittgenstein's later philosophy. (shrink)

In the first full-length study in any modern language dedicated to the Meteorologica, Malcolm Wilson presents a groundbreaking interpretation of Aristotle's natural philosophy. Divided into two parts, the book first addresses general philosophical and scientific issues by placing the treatise in a diachronic frame comprising Aristotle's predecessors and in a synchronic frame comprising his other physical works. It argues that Aristotle thought of meteorological phenomena as intermediary or 'dualizing' between the cosmos as a whole and the manifold world of (...) terrestrial animals. Engaging with the best current literature on Aristotle's theories of science and metaphysics, Wilson focuses on issues of aetiology, teleology and the structure and unity of science. The second half of the book illustrates Aristotle's principal concerns in a section-by-section treatment of the meteorological phenomena and provides solutions to many of the problems that have been raised since the time of the ancient commentators.

In his book The View from Nowhere , Thomas Nagel says that ‘the subjectivity of consciousness is an irreducible feature of reality’ . He speaks of ‘the essential subjectivity of the mental’ , and of ‘the mind's irreducibly subjective character’ . ‘Mental concepts’, he says, refer to ‘subjective points of view and their modifications’ : The subjective features of conscious mental processes—as opposed to their physical causes and effects—cannot be captured by the purified form of thought suitable for dealing with (...) the physical world that underlines the appearances. Not only raw feels but also intentional mental states—however objective their content—must be capable of manifesting themselves in subjective form to be in the mind at all. (shrink)

Acclaimed writer and historian Noel Malcolm presents his sensational discovery of a new work by Thomas Hobbes : a propaganda pamphlet on behalf of the Habsburg side in the Thirty Years' War, translated by Hobbes from a Latin original. Malcolm's book explores a fascinating episode in seventeenth-century history, illuminating both the practice of early modern propaganda and the theory of "reason of state".

En faisant usage des intuitions de la philosophie de la science, l'étude compare les voies d'approches en recherche néotestamentaire et en philologie classique. La recherche néotestamentaire a mis en oeuvre une certaine méthode qui était en vogue en philologie classique durant le 19ème siècle, mais qui fut finalement rejetée par la plupart des philologues classiques. Il s'agit d'une méthode sceptique plutôt que critique, car elle rend toute prétention à la connaissance problématique ou même impossible. Son origine dernière se trouve dans (...) la méthode du doute systématique proposée par Descartes. Telle qu'elle est pratiquée aujourd'hui, cependant, la méthode sceptique est semblable à la philosophie de la science suggérée par le cercle de Vienne en les années 1920, mais que les héritiers de cette école regardent aujourd'hui comme trop simpliste. Des exemples concrets, tirés de la pratique courante de la recherche, montrent comment une méthode sobrement critique peut trouver place dans les études du Nouveau Testament, à condition seulement que les dangers de la méthode sceptique soient clairement aperçus.

Retinoids are low molecular weight, lipophilic derivatives of vitamin A which have a profound effect upon the development of a diverse array of animals. Here, I review these effects on Invertebrates: a colonial hydroid, a colonial ascidian, and Vertebrates: the regenerating amphibian limb, the developing chick limb bud, the regenerating amphibian tail, the anteroposterior axis of the early embryo, the developing chick embryo skin. There is a striking uniformity of effect of retinoids on pattern formation when applied to these diverse (...) organisms. The majority react by being posteriorized in their development, although additional effects can also be seen. Several hypotheses which can explain these results are discussed along with the deduction that they lead to: retinoids may be components of a universal developmental mechanism or they may simply act in a similar way to alter a universal developmental mechanism. In either case the experimental analysis of retinoid effects on development has important implications for the evolution of developmental mechanisms. (shrink)

Discusses Hobbes's relationship with the French mathematician Gilles Personne de Roberval, with whom he became closely associated in Paris during the 1640s. It examines a text that, commonly assumed to be a statement of Roberval's own views, may rather have been a description of the views of Hobbes. The degree to which Hobbes and Roberval were able to assimilate elements of skepticism is also discussed, particularly in relation to the different ways in which they reacted to the experimental evidence for (...) the production of a vacuum in the late 1640s.

I believe that Mr. Sosa is right about my example but wrong on the substantive issue; which shows that my example was poorly chosen. If the ugliest Irishman was so ugly that even the Irish were offended, they might form a committee to get rid of him. Suppose he was kidnapped and deposited in New York. If we were informed of all this and also knew that the ugliest Irishman is the Prime Minister, I agree that we should have been (...) given an adequate explanation of why the Prime Minister is in New York.

Thomas Hobbes is one of the most important figures in the history of European thought. Although interest in his life and work has grown enomrously in recent years, this is the first complete edition of his correspondence. The texts of the letters are richly supplemented with explanatory notes and full biographical and bibliographical information. This landmark publication sheds new light in abundance on the intellectual life of a major thinker.

Malcolm David Eckel takes us on a contemporary quest to discover the essential meaning behind the Buddha's many representations. Eckel's bold thesis proposes that the proper understanding of Buddhist philosophy must be thoroughly religious--an understanding revealed in Eckel's new translation of the philospher Bhavaviveka's major work, The Flame of Reason. Eckel shows that the dimensions of early Indian Buddhism--popular art, conventional piety, and critical philosophy--all work together to express the same religious yearning for the fullness of emptiness that Buddha (...) conveys.

In response to Korn, Huelsman, and Reed's (1992)question, "Who defines those interests, and how serious must the setback be?" (p. 126), we argue that a wrongful (unjust) harm (a setback of interest) is not equivalent to a hurt (a temporary distressing mental state) and that the interests of importance are welfare interests (general means to our ulterior aims), not just a desire to avoid unpleasant mental states (hurts). To set back a welfare interest is to reverse its course or to (...) impede, thwart, defeat, or doom it. It is the primary responsibility of the investigator to define both welfare interests and the risk of harm. An informed consent - one with substantial understanding, in substantial absence of control by others, and given intentionally - allows participants to autonomously authorize participation in research, including their toleration of acts of mental discomfort or distress during an experiment. Not only were our participants not wrongfully harmed, they benefited and were willing to volunteer for future research. No strong evidence has been advanced or linked to guided imagery in a way that would justify its restraint; to so claim evokes a standard of legal paternalism that fails to respect participants' competence and autonomy to choose to participate in research on rape using guided imagery.

Because they failed to include our informed consent, guided imagery scenarios, and debriefing, the relevance of Korn, Huelsman, Reed, and Aiello's (1992) data remains unknown. The design of their Study 1 did not test the greater objectivity of role taking over involved participation. The design of their Study 2 did not demonstrate the effects of demand characteristics. The older "personal acquaintances" were not at higher risk of rape as they claimed. Properly gathered data from the University of Connecticut's laboratory demonstrated (...) that participants regarded the guided imagining of rape to be personally and scientifically beneficial, educating them about the crime and the experience of the rape victim. Prior research had demonstrated that exposure to rape stimuli in combination with debriefing had an educational effect on the decreased endorsement of rape myths. Previously published ethical principles for balancing the rights of scientists, subjects, and society explicate our ethical stance. Informed consent precludes the occurrence of wrongful harms. This poorly designed and poorly reasoned "ethical" critique was unfounded; yet, it might produce a chilling effect on both the use of guided imagery and freedom of inquiry into politically sensitive topics.
